The novel compounds of the invention may be prepared by a variety of methods. They may be prepared, for example, by epoxidiz ing the eorresponding polyethylenically unsaturated ether,"i'.e., anether of an alcohol having an ethylenically unsaturated cycloaliphatic ring and a monohydric alcohol possessing an ethylenic group. 2,3- epoxypropyl 2,3-epoxycyclo-hexyl ether may be prepared by this method, for example, by epoxidiging allyl 2-cyclohexenyl ether. The polyethylenically unsaturated ethers may be prepared by conventional methods from the unsaturated alcohols. Thus, allyl 2-cycl0hexenyl ether may be prepared by reacting allyl chloride with 2-cyclohexenol in the presence of NaOH. 'Di(2-cyclohexenyl) ether of ethylene glycol may be prepared by this method, for example, by reacting 2 moles of 2-cyclohexenyl alcohol with 1 moletof cthylenedichloride in the presence of 2 moles 'N' QI-I- Th ype eI eth ifiee s eaetieh s Pr fe b ee lue ek at i 'e er th ren h 'hem b i 5, C. to C. Solvents are not generally used if excess of the proper reagent is used but may be employed if desired or necessary.

Polyepoxides of the present invention wherein the epoxy group in the vic-epoxy-substituted monohydric alcohol is in the 2,3-position are preferably prepared by first reacting the ethylenically unsaturated cycloaliphatic alcohol with a halo-epoxy-substitjuted compound or a dihalo-hydroxy-substituted co mpoundin the presence of a condensation catalyst to form a ehlorohydr'in ether, dehydrochlorinating that product to form the epoxy ether and then epoxidizing thetether to convert the ethylenic group, in the cycloaliphatic ring to an epoxy group. 2,3-

epoxypropyl 2,3-epoxyzyclohexyl ether maybe preparedby this'method, for example,by reacting Z-cyclohexenol with epichlorohydrin to form the chlorohydrin ether of 2-cyclohexenol, dehydrochlorinating that product to form the glycidyl ether and, then treating the resulting product with a peracid to effect the epoxidation of the ethylenic group in the cyclohexenyl ring.

The condensation may: be effected in the, presence or absence of solvents or .diluentsg In' no'stcases, itis pre ferred to employ a solvent, such as cyclohexane, benzene,l

h l l l Temperatures generally range'from about C. to 150 Q, and more preferably between Q. and C.

The two reactants may be mixed at room temperature andlthe catalyst then added, or thecatalyst may be added to one reactant and the other reactant added 'to' p that mixture. V

The chlorohydrin product obtained by the above' reaction is then treated with an alkalinematerial to dehydrohalogenate the product. This treatment may be accomplished by adding the alkalinematerial'to the reaction mixture obtained in the above described process,

The-condensation reaction described above for the preparation of the 'highermolecular weight products may 'be accomplished by merely heating the components to getherin the presence or absence of inert diluents.

The glycidyl poiyethers of polyhydric phenols obtained by condensin'g the polyhydric phenols with epichlorohydrin as described above are often referred to as ethoxyline resins.

V

The amount of the curing agents employed may. vary over a considerable range depending upon the agent se lected. .With curing agents having replaceable hydrogen, such as the amine curing agents, amounts of agent em.- ployed vary up to and including equivalent proportions, i.e., sufficient curing agent to furnish a replaceable hydrogen atom for every epoxy group to be reacted. In most cases, satisfactory cures are. obtained with from .-7 to 1 equivalent of the curing agent per equivalent of epoxy compound.

Other curing egents, such as metal salts, are employed in amounts varying. from about 1% to about 20%, and more preferably from about 3%. to.20%.

The cure of the polycppxides is preferably .eifected .by

mi h cur ae a e i th pe p x an h n heating. The temperature selected will vary with the curingagent. Active curing agents, suchv as the amines may be utilized, forexa 'ple, atlower temperatures, such as from room-temperat Te toabout 60 C. Less active materials, such as polyasic anhydrides and acids, generally require higher temperatures, such as temperatures ranging frornabout 60 C. to C. Aromatic amines are preferably employed at the higher temperatures, e.g., temperaturesranging fromabout 60 C. to 150 C.

In utilizing the products for this application, it is generally desirable to combine the epoxy material and the curing agent with the desired solvents, and, if desired, other filmforrning materials and driers, and then apply the resulting mixture to the surface to be coated. .Film-forrning materials that can be used with the epoxy material in .this manner include the drying oils, such as tung oil, linseed oil, dehydrated castor oil, soyabean oil, and the like; cellulose derivatives such as cellulose nitrate, cellulose acetate,

cellulose acetate butyrate, cellulose propionate, ethyl cellulose, and the mixtures thereof; and vinyl polymers, such as polymers of vinyl chloride, vinylidene chloride, methyl methacrylate, diallyl phthalate, and the like. ,i'IEhecoatings prepared in this manner may be allowed to set to a hard finish at room temperature or heatmay the applied to hasten the cure. e

The higher molecular weight hydroxy-containing derivatives of the new polyepoxides as described above are particularly suited for use inpreparing coating compositions as described above, as they may be reacted through the hydroxyl group or groups with dryingoil fatty acids or may be ,cured through the hydroxyl groups'with compounds, such as methylol ureas, methylol phenols, .diiso-. cyanates, and the like.

The new polyepoxides and their higher molecular weight derivatives may also be employed with the curing agents to prepare valuable adhesive and impregnating compositions. In utilizing the products for these applications, itis generally desirable to combine the epoxy mar al wi su t b sol en o dilu nts, such a benzen toluene, acetonitrile, andthe like, so as-to form a spread-;

In addition t'o their use in forming theiabovedescribed.

polymeric products, the new polyepoxides and their higher molecular weight derivatives may be used as stabilizing agents for varioushalogen-containing polymers; and par-' ticularly the vinyl halide polymers. These products "are compatible with the polymers-andgin combination therewith give good resistance to discoloration by heat and light. These productsmay be used as stabilizers, alone or in combination with other stabilizing agents, suchas urea and thiourea derivatives. In most cases, the products are effective as stabilizers in amounts varying from about .1% to 5% by weight of the polymer being stabilized. The epoxy material may be combined with the halogencontaining polymer ,by any suitable method, .such as by dissolving the products in a suitable solvent or by milling the products'together a suitable roll mill.
